Tomasz Drwięga 0b5bbf6048 Improve block and transaction propagation (#9954)
* Refactor sync to add priority tasks.

* Send priority tasks notifications.

* Propagate blocks, optimize transactions.

* Implement transaction propagation. Use sync_channel.

* Tone down info.

* Prevent deadlock by not waiting forever for sync lock.

* Fix lock order.

* Don't use sync_channel to prevent deadlocks.

* Fix tests.
